W. Gaus-JR ADJUSTABLE oILER @AEM Patented Sept. 8, 1925.

UNH/En STATES Application iea Apri-1 1',

To altwhcmfe't may concern Be it known that L' VILL'IAM- GnUs,-Jr., a citizen of the United States,` residing at Chicago5 in* the county of Cook anc State ot Illinois, have invented certainV new" and useful mprovements in an Adjustable @iler, of' which the following-is a' specification.-

rlh-isinvention relates tothe lubrication of least springsV 'for' automobiles and other vehicles, and morev particularly to anA adjustable oiler for springs of thisclass which can be varied for springs of different widthsandl thicknessesg The principal object of the invention is therefore to provide an improved adjustable oiler of this kind so thatl when it isA once set for a certain width of springit willremain in that position until adjusted fory a different width.

n the accompanying diawings, Fig. 1 is a top plan of an oiler constructed in accordance with the principlesfof this' invention; Fig. 2A is a' section taken' on the' line 2 2 ot Fig. 1; Fig. 3 is a side elevation ofv the oiler as appliedv to a' leaf spring; Figd is a section take-n on the line 414-41 of Fig. 3; and Fig. 5 is a detail of' one of the oiler sides.

It is desirable to provide an adjustable oiler to accommodate variousV sized springs", and in order to make such an oiler fit properly over the tops of the springs, the sides shouldr set snugly against the edges thereof. The present invention' provides a' screw adjustment for the sections of the top which' may be varied asv closelv as desired within the limits of its adjustment.

Referring more particularly to the drawings, the oiler comprises a pair of angular casing sections i and 5 which are adapted to fit over the upper opposite edges of a leaf spring and to overlap an amount sufficient to provide for a considerable adjustment of these two casing parts to accommodate leaf springs of various widths. One of the casing parts 5 has a raised boss 6 to which an oil cup 7 is attached. The oil cup has a spring pressed lid 8 which is opened against the spring pressure to insert oil within the casing. The overlapping casing member 5 is formed with bent edges 9 adapted to engage under the edges of the other casing member t thereby providing a guide in which it is slidable.

Both of the casing members 4 and 5 are formed at their upper corners with strengthening bosses 10 and at their inner dependingy edges` with -te'eth- 11. tooth 121v at each edger is somewhat longe-r than the others and is'.w inclined andy round'- ed inwardly. At the-lowermost end oeachl casing"` part' is an adjustable extension 13J havinginwalrdly bent edgesy 14- except atl the" top where it is' providedl with'ilateral projections '15 adaptedl to :engage between theA teeth 11.

The`l 'lowermost'l The lowermost teeth 1210i; the 'casings'et and 5 arebent outwardly :and inclined so that' these extensions 13may ybe first inclined outwardly toi-free the projec.-`

tions 15 from engagement with the: teeth and then' adjusted as desired, without actually disenga'ging the extensions 13 from.

the casingparts.

lirorder to adjustY the casings 4e andy 5- Jfor differentl spring widths; an' internally threaded shell 16 is attached to the upper portion of one of the casing parts, anda screw 17 is inserted`v troniIv the outside through the opposite portion ofl the other casing part.- It isi obvious' that the movement of the 'screw in the shell willforce the casing partsr together vand will allow them tobe extended only as .far asA permitted bythe. screw adjustment, `and that whenonce adjusted for `any predetermined width, no. further adjustment is necessary for keepingv the oiler' in this position. Furthermore, thisV screw connection holds' the' casing parts together against loss' or displacement before tlhe oiler is applied to a spring.

lVitlii-n the; casing parts thus assembled;

a continuous pad of felt or other librous absorbent material is inserted, of suiiicient length to extend over the top and against the edges on both sides of a spring to which the oiler is applied and with holes or cutouts at the ends through which fastening bolts for the casing members are inserted.

,If desired, there may be a cut out portion 19 at the top and center of the pad which provides a space for the sleeve 16 and bolt 17 and a. channel Jfor lubricant to the side portions of the oiler and from the oil cup 7. A spacer 20 may be inserted in this cutout portion 19 on top of a leaf spring, and it is preferably U-shaped in cross section fitting the cutout 19 with extensions 2l below the adjacent extremity of the casing section 4f.

To connect the extensions 13 of the casing parts below the leaf spring, a bolt 22 is inserte-d through perforations 23 in the casing `extensions after they are adjusted to bring the bolt up tight against the bottom of the leaf spring, and a nut 24 is drawn up tight. The spring action of the extensions 13 and the sides of the casing section 4c will hold the oiler in place Without danger of'dislodgment.

In applying the oiler to a spring they adjustment of the casing sections 4 and 5 may be made before or after the oiler is applied to the spring by simply tightening the screw 17 in the sleeve V16. The side extensions 13 are preferably adjusted for the spring thickness before the oiler is applied to the spring by engaging the projections 15 with the kproper teeth 11. Another object of the screw adjustment is that the pads 18 can be tightened against the edges of the spring after the oiler has been in use for some time thereby preventing leakage of oil from the sides of the oiler.

I claim: Y

1. In a leaf spring oiler, telescoping casing sections adapted to fit over the edge of a spring, and means within the sections extending over the top of the oiler for drawing the sections together against the edges of a spring.

2. In a leaf spring oiler, casing sections slidable one within the other and fitting over the top of a spring, and fastening means engaging the outer sides of the casing parts adapted to dra-w them together over the top and against the edges of a spring.

l 3. In a leaf spring oiler, telescoping casing parts fitting over the top and against lthe edges of a spring, and means including a threaded shell secured to one of the'casing parts, and a screw extending through the other casing part into the threaded shell for drawing the parts together.

4. In a leaf spring lubricator, a pair of casing parts overlappin over the top of a spring and extending cownward partially over the opposite edges thereof, means for drawing theV casing parts together over the top of a spring, and adjustable extensions at the bot-tom of each casing part.

5. In a leaf spring lubricator, a pair of casing parts overlapping over the top of a spring and extending downward partially over the opposite edges thereof, means for drawing the casing parts together over the out portionk at the center thereof, and a spacer fitting in the cutout portion to prej vent the sides of the cutout portion of the pad from collapsing.

7. In a leaf spring oiler, a pad fitting over the top and downwardly against the sides of a leaf spring and having a cutout portion in the center extending over t-he top of a spring to which it is applied, and spacing means fitting in the cutout portion to prevent. the adjacent sides of the pad from being displaced.

8. In a leaf spring oiler, a sectional casing adjustable over the top of a leaf spring, a pad insertable therein and fitting over the top of a spring in the casing, the pad being formed with a cutout to provide a passage at the top of a spring, means for drawing the sections together, and means within the casing fitting in the cutout portion of the pad to prevent the sides thereof from filling up the passage formed by the cutout when the casing sections are drawn together.
